It is an object of the present invention to provide an inexpensive, efficient pump which can supply lubricating oil by using the revolving motion of an orbiting scroll 2. The pump is so constructed that a piston supported by a fixing member 1 is fitted in a cylinder chamber 102 formed in the inner surface of the end plate 21 of an orbiting scroll 2 which revolves while sliding on said fixing member, by which a pump chamber 104 is defined between them. The piston 101 is extended or retracted depending on the revolving motion of orbiting scroll 2, the volume of said pump chamber 104 is increased or decreased, and a fluid suction port 105 and a fluid discharge port 106 are connected to the pump chamber 104 at predetermined time intervals to supply the fluid.
